Description

Technical Field

[0001] This application relates to the field of shield tunneling spoil treatment, and in particular to a device for preparing non-fired clay bricks from shield tunneling spoil. Background Technology

[0002] Currently, tunnel boring machine (TBM) construction technology is a trenchless method, a fully mechanized construction method within the cut-and-cover tunneling approach. It involves advancing the TBM underground, using its outer shell and tunnel segments to support the surrounding rock and prevent tunnel collapse. Simultaneously, a cutting device excavates the soil in front of the excavation face, and the excavated soil is transported out of the tunnel by haulage machinery. Jacks then apply pressure from the rear to propel the TBM forward, assembling precast concrete segments to form the tunnel structure. The excavated soil and sand enter the cutting chamber, where it is mixed and pumped as high-density slurry to the TBM's slurry treatment system. After treatment, the slurry is pumped back to the excavation face, creating a cycle that allows for the recycling of slurry within the equipment. After being excavated, the slurry undergoes a series of processing steps, including vehicle transfer and brick making. Turning the slurry into bricks allows for better utilization of the slurry.

[0003] In the prior art, a brick-making machine includes a support frame and a feeding frame. The support frame houses an extrusion power assembly. The machine also includes: a lower die base with multiple sets of mold cavity mechanisms, each including a central plate with solid brick cavities and perforated brick cavities, each perforated brick cavity containing a protruding column; and an upper die base with multiple extrusion mechanisms, each including a fixed hanging rod and an extrusion frame, the extrusion frame containing a perforated extrusion plate and a flat extrusion plate. The feeding frame has a collection chamber for injecting the mixed material. A discharge port is located at the bottom of the feeding frame. A support plate is mounted on the feeding frame to support the mixed material. A push plate is mounted on the support plate to push the material into the solid brick mold cavity, and a drive component is mounted on the support plate to drive the push plate.

[0004] Regarding the aforementioned existing technology, during operation, the material on the bearing plate can be pushed into the solid brick mold cavity by the drive component. However, during use, a significant amount of material may not enter the solid brick mold cavity, affecting the material utilization rate. After prolonged use, regular cleaning is required, greatly reducing the ease of use of the brick making machine, which urgently needs improvement. Summary of the Invention

[0005] In order to reduce the occurrence of material detachment from the brick making machine, enable the material to be injected into the brick mold cavity more efficiently, and improve the convenience of using the brick making machine, this application provides a shield tunnel slag non-fired clay brick preparation equipment.

[0006] This application provides a shield tunnel slag non-fired clay brick preparation equipment, which adopts the following technical solution: It includes a mixer for mixing multiple materials, a brick press for pressing the materials, and a conveyor belt for conveying materials between the two. The brick press includes a support frame and a feeding frame. An upper mold base and a lower mold base are vertically mounted on the support frame. The support frame is equipped with a first driving component and a second driving component for driving the upper and lower mold bases. A pushing surface is formed on the lower mold base, and multiple brick mold cavities are opened on the pushing surface. Multiple extrusion seats are arranged at the bottom of the upper mold base, and the multiple extrusion seats correspond one-to-one with the multiple brick mold cavities. A guide cavity for guiding materials is opened on the feeding frame, and a switch assembly for controlling material discharge is arranged at the bottom of the guide cavity. A support plate is provided at the bottom of the material rack. Two pusher plates for pushing materials toward the support frame are slidably connected to the support plate. A pusher drive is provided on the support plate for pushing the pusher plates. A support ramp is provided on the upper side of the pusher plane away from the pusher drive. The support ramp has a support slope that slides with the two pusher plates. The support slope gradually increases upward in the direction away from the pusher drive. The support slope is used to raise the height of the pusher plates. A guide block is provided on the side of the support ramp away from the pusher drive. When the pusher plates are pulled back from the brick press, the guide block is used to guide the two pusher plates away from each other. A tensioning device is provided on the two pusher plates for driving the two pusher plates toward each other.

[0007] By adopting the above technical solution, during use, the mixed material is transported to the guide cavity via a conveyor belt. On the bearing plate, the pusher plate is controlled by the drive component to push the material into the brick mold cavity, so that the material fills the brick mold cavity. When the pusher plate is away from the feeding frame, the height of the pusher plate can be raised by the cooperation of the support inclined surface and the pusher plate, thereby bypassing the material that has not entered the brick mold cavity. With the help of the guide block, the two pusher plates can be pulled back separately. With the help of the tensioning device, the two pusher plates converge and pull back the material. On the one hand, the brick mold cavity can be filled again, and on the other hand, the situation of material falling off the brick making machine can be reduced, so that the material can be injected into the brick mold cavity more efficiently, improving the convenience of using the brick making machine.

[0008] Preferably, a rotating cavity is formed on the side of the supporting inclined surface near the pusher plate, and a guide wheel is rotatably connected in the rotating cavity. The guide wheel smoothly transitions with the pusher plane and the supporting inclined surface.

[0009] By adopting the above technical solution, the guide wheels on the supporting slope can reduce the resistance to the movement of the pusher plate and avoid jamming. At the same time, the guide wheels make the supporting slope and the pusher plane transition smoothly, making the lifting and sliding of the pusher plate smoother and improving the convenience of using the guide wheels.

[0010] Preferably, the pusher plate is inclined downward in a direction away from the pusher drive member.

[0011] By adopting the above technical solution, firstly, this design can enable the pusher plate to push the material more stably, reducing the problem of the pusher plate lifting. While pushing, the pusher plate can press the pusher plane more stably. Furthermore, during the pull-back process, the material can be better pressed into the brick mold cavity, improving the compactness of the material filling.

[0012] Preferably, the two pusher plates are inclined toward the pusher drive member in a direction that keeps them apart from each other.

[0013] By adopting the above technical solution and using a symmetrical tilt design, the material in the middle can be pushed to both sides, improving the convenience of the material entering the brick mold cavity. When pulling back, the material can be gathered towards the center, reducing the accumulation of material on both sides and improving the convenience of pushing the material.

[0014] Preferably, the tensioning device includes a reset seat installed between the two pusher plates, with telescopic cavities on both sides of the reset seat, a telescopic rod slidably connected in the telescopic cavity, a reset tension spring provided in the telescopic cavity, and hinged ball seats provided on both sides of the pusher plates that are close to each other, and a hinged ball head provided on the telescopic rod that is hingedly connected to the hinged ball seat.

[0015] By adopting the above technical solution, the reset spring can pull the two telescopic rods back, and in conjunction with the hinged ball seat and the hinged ball head, the two push plates can be smoothly reset. The hinged structure can adapt to the angle deviation of the push plate sliding and lifting, avoid the push plate jamming, ensure stable and smooth pushing and retraction actions, and improve the stability of equipment operation.

[0016] Preferably, the pushing drive component includes two driving cylinders rotatably connected to the support plate, with each of the two driving cylinders corresponding to one of the two pushing plates. Two support rods are rotatably connected to each driving cylinder, with the rotation axes of both support rods oriented vertically. The support rod near the edge is ball-connected to the pushing plate. A control rod is rotatably connected to the end of the other support rod away from the driving cylinder. A return spring is provided between the control rod and the support rod, and the return spring drives the control rod to rotate closer to the support plate.

[0017] By adopting the above technical solution, the drive cylinder drives the pusher plate to push the material, and the rotating connection structure of the support rod makes the pushing action more flexible and smooth; during the pushing process, the control pressure rod can support the pusher plate, enhancing the overall structural stability. When the pusher plate travels to the support inclined block, it will be lifted and separated. After it separates from the support inclined block, the reset coil spring pulls the control pressure rod to automatically reset.

[0018] Preferably, baffles are provided on both sides of the pusher plate to limit the amount of material discharged from both sides.

[0019] By adopting the above technical solution, materials can be injected more comprehensively into the brick mold cavity, thereby improving the overall material pushing efficiency.

[0020] Preferably, the top of the pusher plate is provided with a cleaning strip for cleaning the bottom of the extrusion seat.

[0021] By adopting the above technical solution, the pusher plate can automatically scrape off the material adhering to the bottom of the extrusion seat when it moves back and forth, effectively preventing the raw materials from sticking and clumping together, eliminating the need for frequent manual cleaning, and improving the convenience of using the cleaning strip.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. During use, the mixed materials are transported to the guide cavity via a conveyor belt. On the bearing plate, the pusher plate is controlled by the drive component to push the materials into the brick mold cavity, so that the materials fill the brick mold cavity. When the pusher plate is away from the feeding frame, the support inclined surface cooperates with the pusher plate to raise the height of the pusher plate, thereby bypassing the materials that have not entered the brick mold cavity. With the help of the guide block, the two pusher plates can be pulled back separately. With the help of the tensioning device, the two pusher plates converge and pull back the materials. On the one hand, the brick mold cavity can be filled again, and on the other hand, the material can be reduced from falling off the brick making machine, so that the material can be injected into the brick mold cavity more efficiently, improving the convenience of using the brick making machine. 2. Firstly, this design allows the pusher plate to push the material more stably, reducing the problem of the pusher plate lifting. While pushing, the pusher plate can press the pusher plane more stably. During the pull-back process, the material can be better pressed into the brick mold cavity, improving the compactness of the material filling. 3. The reset spring can pull the two telescopic rods back, and in conjunction with the hinged ball joint and the hinged ball head, it allows the two push plates to return to their original position smoothly. The hinged structure can adapt to the angular deviation of the push plate sliding and lifting, avoid the push plate from jamming, ensure stable and smooth pushing and retraction actions, and improve the stability of equipment operation.

[0024] The following is in conjunction with the appendix Figure 1 - Figure 7 This application will be described in further detail.

[0025] This application discloses an equipment for preparing non-fired clay bricks from tunnel boring machine slag.

[0026] Example 1 Reference Figure 1A shield tunneling slag non-fired clay brick preparation equipment includes a mixer 1 for mixing various materials, a brick press for pressing materials, and a conveyor belt 2 for conveying materials between the two. The brick press includes a support frame 11 and a feeding rack 4. An upper mold base 10 and a lower mold base 5 are mounted on the support frame 11. A first driving component 14 and a second driving component 13 for driving the upper mold base 10 and the lower mold base 5 are mounted on the support frame 11. A pushing plane 6 is formed on the lower mold base 5, and multiple brick mold cavities 7 are opened on the pushing plane 6. Multiple extrusion seats 9 are installed at the bottom of the upper mold base 10, and the multiple extrusion seats 9 are installed one-to-one with the multiple brick mold cavities 7. A guide cavity 3 for guiding materials is opened on the feeding rack 4. The cross-section of the guide cavity 3 gradually decreases downward along the vertical direction. A switch assembly 15 for controlling the discharge of materials is installed at the bottom of the guide cavity 3. A support plate 12 is installed at the bottom of the material rack 4. Two pusher plates 19 for pushing materials toward the support frame 11 are slidably connected on the support plate 12. A pusher drive for pushing the pusher plates 19 is installed on the support plate 12. A support inclined block 23 is installed on the upper side of the pusher plane 6 away from the pusher drive. A support inclined surface 21 that slides with the two pusher plates 19 is opened on the support inclined block 23. The support inclined surface 21 gradually increases upward in the direction away from the pusher drive. The support inclined surface 21 is used to raise the height of the pusher plates 19. A guide block 22 is installed on the side of the support inclined block 23 away from the pusher drive. The guide block 22 is a triangular block. When the pusher plates 19 are pulled back, the guide block 22 is used to guide the two pusher plates 19 away from each other. A tensioning device for driving the two pusher plates 19 to move closer to each other is installed on the two pusher plates 19. During use, the mixed material is transported to the guide cavity 3 via the conveyor belt 2. On the bearing plate 12, the pusher plate 19 is controlled by the drive component to push the material into the brick mold cavity 7, so that the material fills the brick mold cavity 7. When the pusher plate 19 is away from the end of the feed rack 4, the support inclined surface 21 cooperates with the pusher plate 19 to raise the height of the pusher plate 19, thereby bypassing the material that has not entered the brick mold cavity 7. With the help of the guide block 22, the two pusher plates 19 can be pulled back separately. With the help of the tensioning device, the two pusher plates 19 converge and pull back the material. On the one hand, the brick mold cavity 7 can be filled again, and on the other hand, the situation of material falling off the brick making machine can be reduced, so that the material can be injected into the brick mold cavity 7 more efficiently, improving the convenience of using the brick making machine.

[0027] Reference Figure 4 A rotating cavity 30 is provided on the side of the support slope 21 near the pusher plate 19. A guide wheel 31 is rotatably connected inside the rotating cavity 30. The guide wheel 31 smoothly transitions with the support slope 21 and the pusher plane 6. The guide wheel 31 on the support slope 21 can reduce the moving resistance of the pusher plate 19 and avoid jamming. At the same time, the guide wheel 31 makes the support slope 21 and the pusher plane 6 smoothly transition, making the lifting and sliding of the pusher plate 19 smoother and improving the convenience of using the guide wheel 31.

[0028] The pusher plate 19 is installed at an angle downwards away from the pusher drive component. This design allows the pusher plate 19 to push the material more stably, reducing the problem of the pusher plate 19 lifting up. While pushing, the pusher plate can press the pusher plane 6 more stably. During the pull-back process, the material can be better pressed into the brick mold cavity 7, improving the compactness of the material filling.

[0029] The pusher plate 19 is installed at an angle towards the pusher drive component along a direction that is far apart from each other. The symmetrical tilt design can push the material in the middle to both sides, improving the convenience of the material entering the brick mold cavity 7. When pulled back, the material can be gathered towards the center, reducing the accumulation of material on both sides and improving the convenience of pushing the material.

[0030] Reference Figure 5 and appendix Figure 6 The tensioning device includes a reset seat 25 installed between two pusher plates 19. The reset seat 25 has telescopic cavities 26 on both sides, with telescopic rods 27 slidably connected within each cavity. A reset spring 29 is installed within each cavity. Hinged ball seats 24 are installed on both sides of the pusher plates 19 that are close to each other. Hinged ball heads 28, hinged to the ball seats 24, are installed on the telescopic rods 27. The reset spring 29 can pull the two telescopic rods 27 back, and in conjunction with the hinged engagement of the ball seats 24 and the ball heads 28, allows the two pusher plates 19 to reset smoothly. The hinged structure can adapt to the angular deviation of the sliding and lifting of the pusher plates 19, preventing jamming and ensuring stable and smooth pushing and retraction actions, thus improving the stability of equipment operation.

[0031] The material pushing drive includes two drive cylinders 32 rotatably connected to the support plate 12. Each drive cylinder 32 is installed correspondingly to one of the two pusher plates 19. Two support rods 17 are rotatably connected to each drive cylinder 32, with the rotation axes of both support rods 17 installed vertically. The support rod 17 near the edge is ball-connected to the pusher plate 19. A control pressure rod 18 is rotatably connected to the end of the other support rod 17 furthest from the drive cylinder 32. A return spring 20 is installed between the control pressure rod 18 and the support rod 17. The return spring 20 drives the control pressure rod 18 to rotate closer to the support plate 12. The drive cylinder 32, through the support rod 17, drives the pusher plate 19 to push the material. The rotatable connection structure of the support rod 17 makes the pushing action more flexible and smooth. During the pushing process, the control pressure rod 18 can support the pusher plate 19, enhancing the overall structural stability. When the pusher plate 19 moves to the support inclined block 23, it will be lifted and separated. After it is separated from the support inclined block 23, the reset spring 20 pulls the control pressure rod 18 to automatically reset. With the help of the tensioning device, the pusher plate 19 is closed and returned to the material, ensuring the continuous and stable filling process.

[0032] Baffle plates 16 are installed on both sides of the pusher plate 19. The baffle plates 16 are used to limit the amount of material discharged from both sides. The baffle plates 16 can allow the material to be injected into the brick mold cavity 7 more comprehensively, thereby improving the overall pushing efficiency.

[0033] Reference Figure 7 The top of the pusher plate 19 is equipped with a cleaning strip 8 for cleaning the bottom of the extrusion seat 9. When the pusher plate 19 moves back and forth, it can automatically scrape off the material adhering to the bottom of the extrusion seat 9, effectively preventing the raw materials from sticking and clumping together. This eliminates the need for frequent manual cleaning and improves the convenience of using the cleaning strip 8.

[0034] The preparation process, specifically the following steps; First, the proportion of material is measured and mixed. Based on the raw materials used, the proportion of slag, cement, river sand and fly ash is calculated using a closed weighing hopper. Second, dry mixing: the raw materials are poured into mixer 1 for mixing. During the mixing process, the materials are constantly turned and mixed to eliminate local accumulation of raw materials and make various raw materials evenly blended to form a homogeneous mixture with a dryness and wetness and particle looseness that meet the requirements of brick forming. Third, add water and stir. Add water according to the required moisture content for brick forming. Mixer 1 continuously stirs at low speed to fully mix the water and dry material, eliminate the clumping and stratification of dry material, and make the overall material into a viscous mud-like material with moderate viscosity and good plasticity. Fourth, pressing and shaping: the pusher plate 19 pushes the mixture to the brick press, so that the brick mold cavity 7 is filled with material. Then the upper mold base 10 is started to compact the mixture and form a brick blank. Fifth, maintenance: place it in a natural environment, cover it with geotextile, and keep it moist by adding water.

[0035] The research results show that when the mix proportion is set to 65% slag, 15% cement, 15% fine sand, and 5% fly ash, the compressive strength of the unfired bricks is 10.6 MPa to 11.9 MPa, and the softening coefficient is 0.80 to 0.87; when the mix proportion is set to 58% slag, 22% cement, 15% fine sand, and 5% fly ash, the compressive strength of the unfired bricks is 15.2 MPa to 15.9 MPa, and the softening coefficient is 0.80 to 0.85; when the mix proportion is set to 50% slag, 30% cement, 15% fine sand, and 5% fly ash, the compressive strength of the unfired bricks is 20.3 MPa to 20.8 MPa, and the softening coefficient is 0.81 to 0.84. The material ratio in this application is 50% slag, 30% cement, 15% fine sand, and 5% fly ash. The compressive strength of the finished bricks is greatly improved, the brick blanks are not easy to crack or chip, and the load-bearing and erosion resistance is stronger. They can be adapted to various construction conditions such as outdoor paving, foundation pit backfilling, and wall construction, and the finished bricks have a longer service life.

[0036] The implementation principle of the shield tunnel slag non-fired clay brick preparation equipment in this application embodiment is as follows: During production, the proportion of shield tunnel slag, cement, fine sand and fly ash is first accurately calculated, and then the raw materials are fed into the mixer 1 for mixing. The mixture is conveyed to the guide cavity 3 by the conveyor belt 2. The guide cavity 3 is wider at the top and narrower at the bottom, which can gather the material. The bottom switch assembly 15 feeds the material to the bearing plate 12 at timed intervals. The pusher plate 19 pushes the material forward under the drive of the drive cylinder 32. The baffle plates 16 on both sides of the pusher plate 19 prevent the material from leaking out. During the pushing process, the control pressure rod 18 can support the pusher plate 19. Material is pushed to fill the brick mold cavity 7. When the pusher plate 19 moves to the position of the support inclined block 23, the support inclined surface 21 lifts the pusher plate 19 to pass over the material that has not entered the brick mold cavity 7. When it has traveled a certain distance, the drive cylinder 32 drives the pusher plate 19 to retract. At this time, the guide block 22 can pull the two pusher plates 19 back separately. In conjunction with the reset spring 29, the two pusher plates 19 automatically close together in the middle and pull back the material, thus refilling the material that has not entered the brick mold cavity 7. After the material filling is completed, the first drive is started. The moving part 14 drives the upper mold base 10 to press down, pressing the material in the brick mold cavity 7 into a brick blank under high pressure. When the pusher plate 19 moves back and forth, the top cleaning strip 8 simultaneously scrapes off the material stuck to the bottom of the extrusion seat 9, eliminating the need for manual cleaning and greatly improving the convenience of brick making operations. The pusher plate 19 is designed with a structure that can be pulled back twice, which can refill the brick mold cavity 7 on the one hand, and reduce the occurrence of material falling off the brick making machine on the other hand, so that the material can be injected into the brick mold cavity 7 more efficiently, improving the convenience of using the brick making machine.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
